Hi, checking and unchecking the "Merge result" does not seem to do anything on the screen. "Help" also does not mention about this option in the documentation. What does the "Merge result" option under Thicken do?
Same thing it does on every other feature.
If you already have a solid body in your model, and you create another feature that adds (rather than subtracts) material, you have the option to "merge result" such that the new material is added to the existing body if it contacts or intersects the existing body, or not to merge, in which case the new material becomes a separate body. If the resulting new body doesn't contact the existing body, or there is no existing body, there is no difference when checking or unchecking the box.
